EYEGLASS-MOUNTING.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed April 4, 1914. Serial No. 329,461.

To all whom it at (17 concern Be it known that 1, ANDREW J. MORRARTY,

a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode island, have invented certain new and useful Improvements in Eyeglass-Mountings, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to finger-piece'eyeglass mountings, and with respect to certain more specific features thereof to actuating springs therefor.

It is one of the objects of the invention to provide an extremely simple and practical mounting of the character referred to.

Another object of the invention is the provision of compact actuating means for the finger-operated nose grippers or so-called guard levers.

Another object of the invention is to provide an actuating spring of an improved type and one which is inexpensive to manufacture.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts, which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein there is shown one of various possible embodiments of the invention, Figure 1 is an enlarged plan view of an improved fingerpiece eyeglass mounting; Fig. 2 is a view in front elevation of the same; Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. 1. Figs. 1, 5, 6, 7'and 8 are views showing the development in the construction of an actuating spring for finger-piece eyeglass mountings.

Referring now more particularly to the drawing, in which similar reference characters refer to similar parts throughout the several views, there is indicated at 1 a bridge member, the same being provided with the usual forked ends 2 and lens-retaining member 3, both adapted to cooperate to hold the lens securely in fixed position relative to said bridge 1. The usual screw or rivet 5 is passed through the lens connecting the oppositely disposed forked ends 2. A seat 6 is formed on the bridge member 1 adjacent the retaining member 3 and mounted upon said seat is a lever 7 having a manipulating end S and a nose grip end 9, carrying the supplemental nose grip 10. It is desirable in eyeglasses of this character to use some means, preferably a spring, to cause the nose grip to be constantly urged away from its associated lens; or in other words, to be constantly urged toward the nose of the wearer. To accomplish this advantage in an improved style, is one of the objects of this invention, and a spring 11 is accordingly provided comprising a coiled body portion 12 and a head or washer portion 13 formed integral with the body portion. Opposite end portions 14 and 15 are provided, the end 11 being adapted to engage with the retaining member 3 or the lens 1, and the end 15 being formed to suitably engage the lever 7. This spring is preferably constructed from a length of round spring wire flattened, the flattened length being bent edgewise as indicated in Fig. 6. bringing the portions on opposite sides of the bend into a staggered position or relation. It will be seen that by this step in the process a short leg 16 is provided on one side of the bend and a long leg 17 is provided upon the opposite side. The next step in the method contemplates the bending of the two legs at right angles to each other. as indicated in Fig. 7 of the drawings. The blank is then preferably wound upon a mandrel, the flat portion 16 being bent into a volute or coiled washer or head portion. and by continued winding in the same direction the coiled body portion is formed (Fig. 8). It will be noted that by this construction a portion.

18 of the top edge 19 ofthe spring 11 inclines gradually toward the point where the coiled body portion of the spring connects with the washer member 13. It will be obvious that by this construction the head 20 of the retaining screw 21 will bear against the top edge 19 of the spring 11 except where the said top edge is inclined away from the plane of the top of the coil as indicated at 18. Directly opposite this portion of the topedge of the spring is the intcgral connection of the coiled body portion 12 with the washer 13, and it is highly desirable to avoid contact of the retaining member at this point for the reason that.

attachment may be temporary as'by threading the shank 22 into the bridge, or it may be of a more or less permanent character, as by bending over the end of the retaining member as indicated at 23.

It will be noted that the washer member '13 merges with the inner end of the coiled body portion of the spring, and that said washer portion extends outwardly and has an exterior diameter substantially the same as the diameter of the largest coil of the body portion. When the retaining member is in place the coiled body portion of the spring lies between the head 20 of the retaining member and the washer 13. The washer 13 in turn rests upon the guard lever 9. The spring is consequently substantially dirt proof, and when the glasses are being cleaned this construction minimizes the possibility of the spring becoming entangled with the cloth or material being used to cleanse the eyeglasses.

It will be seen from the foregoing that a device is provided which accomplishes, among others, all of the objects and advantages hereinbefore set forth.

As many changes could be made in carrying out the above method, and in the above construction, and many apparently widely diiferent embodiments of this invention could be made without departing from the scope thereof, it'is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of Ian guage,might be said to fall therebetween.

-Having described my invention, what I claim as new and desire to secure by Letters Patent is:

In an eyeglass mounting, in combination, a support, a lever associated therewith and a spring disposed to turn said lever relative to said support, said spring compris ing a volute resilient body portion and a volute head portion integral with said body portion and voluted to lie in a plane transverse of the plane of the volution of the body portion.

2. In an eyeglass mounting, in combination, a support, a lever associated therewith,

a spring disposed to turn said lever relative to said support, said spring comprising a volute resilient body portion and av'olute head portion integral with said body portion and volutedto lie in a plane transverse of the plane of the volution of the body portion, and said portions comprising means whereby they may respectively engage said lever and said support.

3. In an eyeglass mounting, in combination, a support, a lever associated therewith, a spring disposed to turn said lever relative to said support, said spring comprising a volute resilient body portion and a volute head portion integral with said body portion and voluted to lie in a'plane transverse of the plane of the volution of the body portion, and a retaining member having an enlarged portion'adapted to extend opposite and adjacent the outer edge of saidbody portion.
